I'm a personal trainer and this five-move dumbbell workout will build muscle all over in 20 minutes

If you’re short on time but want to target every major muscle group this 20-minute workout is perfect.

I'm a personal trainer and I've selected five of my favorite movements—many of them compound exercises—to work your entire body. All you need is a pair of dumbbells at a weight that’s challenging for you. That may mean choosing a different weight for each exercise, which is why adjustable dumbbells are worth buying. Fit&Well's top three adjustable dumbbells are at the bottom of this article.

Don’t forget to spend five to 10 minutes warming up and cooling down.

Why you should do full-body workouts

Full-body workouts are a great way to make sure you are training all the major muscles and building strength evenly. You'll also burn more energy in your workout than following a split routine where you focus on a single body part in a workout, since more muscle mass is used during full-body workouts.

If weight loss is a goal, focusing on full-body workouts is a great way to increase calorie burn. Plus, doing compound moves has been shown to trigger a greater metabolic response compared with isolation exercises like biceps curls or triceps extensions.

Whether you’re looking to build muscle or burn body fat, a full-body workout with compound moves is one of the most time-efficient and effective ways to achieve this. For a longer session once you've mastered this routine, try this full-body dumbbell workout.

Shop adjustable dumbbells

Adjustable dumbbells are a great addition to a home gym because you can quickly adjust the weight for each exercise. To build muscle the last few reps of each set should feel challenging—that's impossible to achieve for every exercise if you only have one pair of fixed-weight dumbbells. Fit&Well has been testing the best adjustable dumbbells since 2020, here are our current favorites.
